May Jones (Dracco).

Vlad found himself with anti-personnel mines. Yes, ordinary anti-personnel mines. He skillfully placed them directly on the Kraken, waited for them to be drawn into the vacuole, and the mines exploded. May's rifle didn't do much damage, but the exploding bullets turned out to be effective in this regard. Nevertheless, the Kraken continued its dark work: it was sucking in the boat. It succeeded, and it started on Vlad. And now May was left alone, barely managing to pull the trigger and reload her weapon; the last shot was just enough to finally pierce the amoeba and cause an unstoppable cytoplasmic flow. The giant blob simply began to melt before their eyes.
